What is the lesser sac also referred to as?

The lesser sac is also known as the omental bursa. This space is located behind the stomach and the lesser omentum, and it allows for movement and expansion of the stomach and other adjacent structures. The omental bursa plays an important role in the anatomy of the abdominal cavity, providing a compartmentalized area that can be significant during surgical procedures or in the context of disease processes. Understanding the anatomy of this space is crucial for recognizing how different structures within the abdomen interact and relate to one another.

The other terms listed refer to different anatomical structures or conditions. Omphalocele is a congenital condition related to the abdominal wall where the intestines protrude into a sac outside the body. The term peritoneal pouch may refer to various recesses within the peritoneal cavity but does not specifically indicate the lesser sac. Visceral cavity is a broader term that generally describes spaces containing internal organs, not specifically the lesser sac.
